Description
Here we present the results of a wide-field (˜36 sq. deg.) near-infrared (ZYJHK) survey of the Praesepe cluster using the Data Release 9 (DR9) of the UKIRT Infrared Deep Sky Survey (UKIDSS) Galactic Clusters Survey (GCS). We selected cluster candidates of Praesepe based on astrometry and photometry. With our candidate list, we have obtained the luminosity function of Praesepe in the Z and J bands, and we have derived the mass function (MF) of Praesepe from 0.6 down to 0.072 M⊙. Moreover, we have estimated the binarity of the Praesepe members in the 0.5-0.1 M⊙ mass range and as well as their variability.

    Performance of the image persistence model for Euclid infrared detectors
    Large-format infrared detectors are at the heart of major ground and space-based astronomical instruments, and the HgCdTe HxRG is the most widely used. The Near Infrared Spectrometer and Photometer (NISP) of the ESA's Euclid mission launched in July 2023 hosts 16 H2RG detectors in the focal plane. Their performance relies heavily on the effect of
